Internet abuse, particularly cybercrime, continues to grow in every corner of the domain name registration system. As cybercriminals increasingly weaponize domains, regardless of top-level domain (TLD), WhoisXML API launched the Data Exchange Program for Internet Abuse Prevention.
The program smooths out and expedites the collection and dissemination of critical domain, DNS, and IP intelligence between TLD registries, registrars, and other key Internet community members to reduce and prevent Internet abuse.
The Data Exchange Program for Internet Abuse Prevention is open to all ccTLD, gTLD, and new TLD registries and registrars worldwide.

Stay alert to the most prominent Internet abuse trends as identified through the collaborative efforts between ccTLD, gTLD, and new gTLD registries and registrars worldwide.
We have billions of historical WHOIS and DNS lookup records spanning the vast majority of TLDs and active IP addresses. Our collective intelligence results from more than a decade of data crawling and gathering, and it continues to grow daily with every data update and partnership.
Identify regular offenders who repeatedly figure in Internet abuse instances, along with the available domains, IP addresses, and other cyber resources associated with them.
We understand that key members of the Internet community are scattered across the world, and obtaining unified data is hard work. WhoisXML API and our partners’ comprehensive data sources can help you:
We provide some of the most comprehensive and complete DNS, IP, and WHOIS data sources that include:
